* Add metrics related to devp2p peer connections * Avoid reconnecting to peers that just failed connection - Add SeenTable to avoid reconnecting to peers immediately after a failed connect. Depending on the failure, the amount of time is different. This is similar to what is done in nimbus-eth2. - Attempt to rework rlpxConnect at the same time, in order to make sure that errors are properly handled. The current structure is far from ideal, but it is hopefully a small step in the right direction. To many oddities in there right now to really rework rlpxConnect properply. * Fix rlpx thunk fuzzer
